Device for implementing colorectal surgery, and control method

Abstract

The invention belongs to the technical field of rectal surgical instruments, and discloses a device for implementing colorectal surgery, and a control method. In the device for implementing the colorectal surgery, a handle is hollow; a connecting pipe is integrally arranged at the lower end; the outer side of the lower half section of the connecting pipe is sleeved with a supporting sleeve; the supporting sleeve, the connecting pipe and the interior of the handle are communicated; a supporting air bag is fixed to the inner wall of the supporting sleeve; an inflation device is arranged at the air inlet end of the supporting air bag; a negative pressure machine is arranged at the upper end of the handle; the negative pressure machine is communicated with the interior of the handle; and a drainage pipe is arranged at the outlet end of the negative pressure machine. According to the device in the invention, after the supporting sleeve enters the rectum, the supporting sleeve is supported through the supporting air bag, so that the pain of a patient is relieved; the rectal mucosa is opened through arranged bulges; ruga is reduced; the rectal mucosa is pulled; furthermore, the mucosa isfixed to an annular block through a fixing block; therefore, the mucosa at the anus can be easily and safely cut open; the stripping integrity of the mucosa is improved; and meanwhile, the clearness and cleanness of an operation field are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of rectal surgery, and in particular relates to a device and a control method for performing colorectal surgery. Background technique [0002] At present, colorectal cancer is a common malignant tumor in the gastrointestinal tract. The early symptoms are not obvious. With the enlargement of the cancer, symptoms such as changes in bowel habits, blood in the stool, diarrhea, alternating diarrhea and constipation, and local abdominal pain appear. In the late stage, anemia is manifested. , weight loss and other systemic symptoms. Colorectal cancer surgery requires complete dissection of the rectal mucosa and dissection of the rectum, and dissection of the rectal mucosa requires surgery from the anus. In previous operations, local suture traction and electric knife stripping were the mainstream, but the rectal mucosa was easily left in case of inadvertence. Due to the large storage of colorectal bacteria, asept...

Problems solved by technology

[0003] Through the above analysis, the existing problems and defects of the prior art are: in the existing rectal mucosal separation, the mucosal stripping is incomplete, and the surgical site is easily polluted.
